Patent JP-H0818102-A (JP)
Title: Semiconductor light emitting element
Inventor: OTSUKA KOJI
IPC: H01S5/00
Filed: 1994-07-01
Abstract: PURPOSE:To improve luminunce performance and brightness by forming the thickness of the first clad layer at the thickness that quantum mechanic tunnel effect does not occur. CONSTITUTION:The (n)-type and (p)-type clad layers holding an active layer 4 are constituted of first (n)-type and (p)-type clad layers 3a and 5a having the relative lower carrier concentrations and second (n)-type and (p)-type clad layers 3b and 5b having the concentrations higher than those of the layers 3a and 5a. Furthermore, the thickness of the first (n)-type and (p)-type clad layers 3a and 5a are formed at the thickness so that quantum mechanic tunnel effect does not occur. Thus, the carrier, which is inplanted into the active layer 4, can be coufined in the active layer 4. Furthermore, the formation of the mixed crystal of In in the first (p)-type clad layer 5a is made smaller than the second (p)-type clad layer 5b. In this way, the energy gap of the first (p)-type clad layer 5a is broadened. Therefore, the decline of the potential barrier caused by the decrease in carrier concentration is compensated and the potential barrier between the active layer 4 and the (p)-type clad layer 5a can be made high.

Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To control power source which does not have a control power source capable of operation always with a relay and to eliminate influence on instantaneous cut. SOLUTION: When the switch 6a of a manual operation is made, input power 11 is supplied to the coil 4c of the relay 4 with two contact points and the contact points 4a and 4b are closed. When the contact point 4b is closed, power is supplied to the power source 2 of a main body device and the power source 2 is started. Then, power is supplied to a latching relay 7 with the output of the power source 2 after the power source 2 is once started, the contact point of the latching relay 7 is switched and a power supply route for the power source 2 is changed. Thus, the latching relay 7 is not closed as long as the output of the power source 2 is held even if the input power 11 is instantaneously cut by setting the output of the power source 2 of the main body to be the power of the latching relay 7.

Title: Compressor
Inventor: UENO FUMITO
IPC: F04C29/04
Filed: 1981-10-29
Abstract: PURPOSE:To simplify the structure of a compressor by making a common use of an injection gas passage constituting an element of a capacity increasing mechanism and a capacity controlling passage constituting an element of a capacity decreasing mechanism and to prevent chattering of a control valve disposed in association with these two passages. CONSTITUTION:In association with a control valve 14 which serves as an essential element for controlling the capacity of a compressor, a capacity control port 9 constituting an element of a capacity decreasing mechanism and an injection port 10 constituting an element of a capacity increasing mechanism are provided in the manner that a by-pass passage and an injection passage are used commonly with each other. Therefore, the piping system for controlling the capacity of the compressor is simplified and the number of component parts can be reduced, so that the manufacturing cost of the compressor can be lowered as a whole. Further, since only the intermediate-pressure gas used as control gas is acted to a piston valve 16 of the control valve 14 as a back pressure and no influence is exerted by the pressure in a cylinder chamber 1a at the time of capacity controlling operation of the compressor, chattering of the valve can be prevented in a reliable manner.

Title: Electronic computer
Inventor: KOBAYASHI JIYUNJI
IPC: G06F3/12
Filed: 1982-10-06
Abstract: PURPOSE:To add a simple typewriter function to an electronic computer, by having a display only and inhibiting the printing and output in case an error arises with a device which displays, prints and delivers the results of operations fed to an input part. CONSTITUTION:An input part 1 contains keys of digits (0-9), the alphabet (A-Z) and special characters (%, +, -, X, divided by , etc.) respectively. When an operation is indicated and fed to the part 1, a control part 2 sends the data to a store part 3 and an operation command to an arithmetic part 4 respectively. When an operation is through in a normal way, the result of operation is sent to the part 2. At the same time, a signal 1 showing no generation of errors is sent to a print control part 6. The part 6 comprises an AND circuit, and a print command signal 1 is supplied to the AND circuit. A display part 5 displays the result of calculation, e.g., ''2+15=17'' and also an error if generated. The part 4 transmits a signal ''0'' to an AND6 when an error is generated to inhibit the output of a print output part 7. Thus an electronic computer functions with high efficiency as a simple typewriter.
